You did read the article right? 900 feet, Magnitude +15.0
That's dim. Very, very, very dim. You will not see it with your eyes alone, and you're going to need a very big telescope to see it with your
Most of these objects are spotted by pictures. A picture is taken of the sky with a telescope. The longer exposure allows very dim and small objects
like this to appear in the picture.
Then another picture of the same area of the sky is taken the next night at the same time.
THEN the 2 pictures are compared to see if any of the "stars" appear to move against the back ground of known, fixed stars. If something does, then
you've discovered something.
This is a tedious process, and you may, or may not see something. If the object had been further away, and was even dimmer than Mag +15.0, it may not
have shown up in that picture of that sky, and not discovered.
